I finally remembered one that my son used to use to scare his little sisters. Years ago, he was a great fan of Dr. Who, I wasn't, but apparently there was some sort of creature they all knew from the show, called the Bumanji.

Anyway whenever we would go through the automatic carwash and the long thick strips of fabric would begin to sway and shimmy their way towards the windshield, Colin would tell his sisters it was the Bumanji coming to get them. We still joke about it whenever we get the cars washed.
